A joint analysis of Planck and BICEP2 B modes including dust polarization uncertainty
Michael J. Mortonson, Uroš Seljak
We analyze BICEP2 and Planck data using a model that includes CMB lensing, gravity waves, and polarized dust. Planck dust polarization maps have highlighted the difficulty of estim…
Dark Energy: A Short Review
Michael J. Mortonson, David H. Weinberg, Martin White
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades. In this short review, we briefly summarize theories for the origin of cosm…
Probing the Circumgalactic Medium at High-Redshift Using Composite BOSS Spectra of Strong Lyman-alpha Forest Absorbers
Matthew M. Pieri, Michael J. Mortonson, Stephan Frank +17
We present composite spectra constructed from a sample of 242,150 Lyman-alpha (Lya) forest absorbers at redshifts 2.4<z<3.1 identified in quasar spectra from the Baryon Oscillation…
WFIRST-2.4: What Every Astronomer Should Know
D. Spergel, N. Gehrels, J. Breckinridge +43
The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. The report of the WFIRST-AFTA Science De…
Testing dark energy paradigms with weak gravitational lensing
R. Ali Vanderveld, Michael J. Mortonson, Wayne Hu +1
Any theory invoked to explain cosmic acceleration predicts consistency relations between the expansion history, structure growth, and all related observables. Currently there exist…
Observational Probes of Cosmic Acceleration
David H. Weinberg, Michael J. Mortonson, Daniel J. Eisenstein +3
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of "dark energy" with…
